Hello,
I have some discovery rules setup which work only by running a simple ping.
The discovery rule runs once every 2 minutes on the network (120 sec) like so

There are other actions set up that may or may not add what was discovered as hosts, but these are not important for this issue.
The issue I have is that Zabbix will report released IPs as being "down", even though these are not monitored hosts. This appears in the Discovery Status on the main dashboard.

I have set up an action which removes "hosts" when downtime is equal or higher than 172 800 seconds (which is 2 days).
This action however does not work for removing these released ips from being reported as down, nor should it, since these are not actual monitored "hosts". They simply appear in the list because something responded to ping at this address at some point in the past.
It is obvious the engine can recognize and treat unused ips differently, since it doesn't just issue a "down" alert for every free ip in the scanning range. It just does so for addressed that have been used at some point in the past. So, is there any way of making Zabbix treat these released IPs as simple unused IPs after a certain amount of time, and stop reporting them as being "down" ?
